N2 - Most iron meteorites are thought to be remnants of the cores of differentiated planetesimals, exposed to interplanetary space by collisional events. Many display a Widmanstätten pattern, an intergrowth of kamacite (bcc α-iron) and a high Ni-iron material called taenite. This coarse structure, which is formed by slow cooling over millions of years in space, may influence the material properties and failure mechanisms. In this study, eight samples are used to characterize the strength and failure mechanism of the Gibeon (IV) iron meteorite under quasi-static compressive and tensile loading. Here is shown the full-field strain and displacement contours using an in-situ three-dimensional digital image correlation (DIC) technique that provides insights into the initiation and propagation of damage. Further microstructural characterization of the post-fracture surfaces is conducted and correlated to the DIC effective strain contours to better investigate the influence of the different phases on the failure mechanisms.
